a dangerous operation (such as header backup restore or formatting a supposedly non-system device) never
at WM_INITDIALOG or any other GUI events -- instead call IsSystemDevicePath (path, hwndDlg, FALSE) for
very fast preliminary GUI checks; also note that right after the "Select Device" dialog exits with an OK

/* Determines whether the device path is the path of the system partition or of the system drive (or neither).
If bReliableRequired is TRUE, very fast execution is guaranteed, but the results cannot be relied upon.
If it's FALSE and the function is called for the first time, execution may take up to one minute but the
results are reliable.
IMPORTANT: As the execution may take a very long time if called for the first time with bReliableRequired set
to TRUE, it should be called with bReliableRequired set to TRUE only before performing a dangerous
operation (such as header backup restore or formatting a supposedly non-system device) never at
WM_INITDIALOG or any other GUI events (use IsSystemDevicePath(path, hwndDlg, FALSE) for fast
preliminary GUI checks; also note that right after the "Select Device" dialog exits with an OK
return code, you can use the global flags bSysPartitionSelected and bSysDriveSelected to see if the
user selected the system partition/device).
After this function completes successfully, the results are cached for the rest of the session, bReliableRequired
is ignored (TRUE implied), repeated executions complete very fast, and the results are always reliable.
Return codes:
1 - it is the system partition path (e.g. \Device\Harddisk0\Partition1)
2 - it is the system drive path (e.g. \Device\Harddisk0\Partition0)
3 - it is the extra boot partition path
0 - it's not the system partition/drive path
-1 - the result can't be determined, isn't reliable, or there was an error. */
